Fig. 2 is the utility model thermal energy recoverer structural representation.
Detailed description of the invention
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with detailed description of the invention, the utility model is described in further detail.
A kind of steam boiler steam discharge energy recycling system, comprise: boiler 1, oxygen-eliminating device 2, thermal energy recoverer 3, blowdown drum 4, pollution discharge pond 5, as shown in Figure 1, 2, wherein, described thermal energy recoverer 3 comprises shell 9, jet chimney, flash vessel, receipts energy device, and flash vessel and receipts energy device have several, connect in the mode of cascade; Described receipts can be provided with heat exchanger 7 in device inside, and it is formed in the mode of permutation and combination, is vertical-shaped structure; Described shell 9 is provided with pure water water inlet, pure water delivery port, steam inlet and blowdown steam (vapor) outlet.Described boiler 1 drainpipe outlet is connected with flash vessel water inlet, receipts energy device one end outlet in described thermal energy recoverer 3 is connected with described oxygen-eliminating device 2 one end entrance, the other end is exported and is connected with blowdown drum 4 by valve, described oxygen-eliminating device 2 one end entrance is connected by the water inlet of valve with the flash vessel in described thermal energy recoverer 3, the outlet of described oxygen-eliminating device 2 is connected with the entrance of described boiler 1, and described blowdown drum 4 is connected with described pollution discharge pond 5.
The utility model is received in energy device by the steam be discharged in air is guided to, steam is at receipts energy device adduction energy, sewerage heat energy through continuous blowdown flash tank is utilized, heat simultaneously through the sewage of regular unloading container is also utilized, and then reach comprehensive utilization, as calculated, benefit is reclaimed considerable:
Calculate according to utility boiler blowdown rate, consider overhaul of the equipments, stop using and variable parameter operation factor, if the total piston displacement of two hydrophobic development units is 700kg/h, 260 DEG C of water enthalpies are 2994.1kJ/kg, it is 334.97kJ/kg that receipts energy device blends coolant-temperature gage 80 DEG C of water enthalpies, if receiving device cold in-water temperature 20 DEG C of water enthalpies to be 83.96kJ/kg, so:
Heat-recoverable: 2994.1kJ/kg-334.97kJ/kg=2659kJ/kg;
Water absorbs heat: 334.97kJ/kg-83.96kJ/kg=251.01kJ/kg;
Need cooling water inflow: 700kg × 2659kJ/kg ÷ 251.01kJ/kg=7415.24kg/h;
Annual heat-recoverable: 700kg × 2659kJ/kg × 7000h=13.02 × 1010kJ/;
The whole year can save coal: 11.898768 × 1010kJ/ ÷ 29310kJ/kg=444 ton;
Mark coal per ton is by 600 yuan of calculating, and year can economize on the use of funds: 444T/ × 600 yuan/T ÷ 10000=26.64 ten thousand yuan; Demineralized water reclaims by 6 yuan of calculating per ton, 0.7T × 7000h × 6 yuan of can economizing on the use of funds/T=2.94 ten thousand yuan; Add up to Spring Festival holidays money: 26.64+2.94=29.58 ten thousand yuan.It is 29.58 ten thousand yuan that year reclaims general economic value.Investment correlative charges about about 100,000 yuan, its investment can be regained in a short time, considerable benefit.
